JOSEPH PETITHOMME, OF SACRAMENTO, CALIFORNIA.

CAR AXLE BOX.

SPECIFICATIGN forming part of Letters Patent No. 344,401. dated June 29, 1886.

Application filed January 5,1886.

To aZZ whom it may concern.-

Be it known that I, J osnrrr Prxrrrnomrn, a resident of Sacramento, in the county of Sacramento and State of California, have invented a new and useful Oil-Tight and Dust Proof Journal-Box; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings.

My invention relates to means for providing ajournal-box for railway-cars, which will effeetuallyhold oil and exclude dust and grit.

The following description fully explains the nature of my said invention and the manner in which I proceed to construct, apply, and use the same, the accompanying drawings being referred to by figures and letters.

Figure 1 represents elevation of the j ournalbox, showing the axle broken offand the spring arrangement for the lid. Fig. 2 represents elevation of the same, as seen from the right hand of Fig. 1. Fig. 3 represents a section of the lid, showing the coiled spring and attachment. Fig. etgives two views ofthe hinge bolt and coiled spring with the upper part of the hinged lock-lever Fig. 5 represents a sec tion through the middle of the journal-box. Fig. 6 represents a cross-section of the journalhox. Fig. 7 gives two views of the sliding casing containingthebrass padding. Fig. 8 gives two views of the upper movable brass padding and the lower stationary brass padding. Fig. 9 represents elevation of the intermediate piece between thesliding casing and the lower spring. Fig. lOgives three views of the combination-washer. Fig. ll is a view or" the brass plate in washer.

In constructing a journal-box which will hold the lubricating-oil and exclude all dust and grit, a sliding casing, a, is provided which slides into a recess or slot, 5, in the upper inner end ofthe journal-box a. The casing fits around the axle k, and has a slot, :0, for the insertion of the upper spring, 8, and the upper movable brass padding, 0, the ends of which work in the lower extension of the slot. At the upper end of the sliding casing there is a leather packing, 1;, held to the casing by a strip of metal,which is riveted. In a slot on the lower end of the inner side of the casing is the stationary brass padding 1), the upper inner edges of which are cut in for the move ment of the lower edges of the upper brass padding. A combination-washer, t, fits into a recess or slot, y, in the lower end of the outside of the casing, and is composed of a crescent-shaped leather pouch in which there is a brass or metallic plate, a. An intermediate piece, q, conforms in shapeto the lower end of the casing and tits against it, and to this piece the lower spring, 1', is riveted. The combination-washeris keptin position against the axle by the action of the spring 0*, the spring being held against the intermediate piece, which fits to the casing by a set-screw, w, by which the washer is adjusted. A lid, 1), is attached to a lug on the top of the outer end of th e journal-box by a hinge-bolt, e, which passes also through a lug on each side of the lid, the end of the bolt being held by a nut, 73. On the threaded end of the bolt the head of the lock-lever dis attached, between the square shoulders of which the head of the lever enters, and is held by a pin. The arm of the lever when the lid is closed is held by a catch, 9', on the edge of the journal-box. Under the lid one end of a coiled spring, f, is held to the hinge-bolt cby ascrew, and after coiling around the bolt the other end passes through the eye of a bolt, which goes through the lid and is held by a screw. The under side of the lid is covered with a leather packing over which a 'metal plate is placed.

The operation of my device is as follows: The arrangement of the spring 8 over the up per brass padding keeps the padding in contact with the axle, and the spring 1", under the sliding casing, causes continuous contact of the stationary padding p and the combinationwasher twith the. axle at its lower half-circle. The springs in use do not effect the perfect and continuous contact between the axle and the washer which is produced by my device. Lost motion caused by the wear of the parts is prevented by the action of the set-screw w, whichworks against the lowerend of the sliding casing and adjusts the combination-washer to the axle. By this arrangement the oil is retained in the box and the journal is kept in good condition.

By the arrangement of the lid 1) having a bination with the intermediate piece, q, slida ing casing 42, upper movable brass padding, 0, lower stationary brass padding, 9, lower spring, r, and upper spring, 8, substantially as described and set forth.

2. In a lid for a journal-box, the hinge-bolt cl, having coiled springf attached, in combination with the lock-lever cl, lever-arm e, and catch j, substantially as described.

3. In an oil-tight and dust-proof journalbox for railway-cars, the combination of washer t, and brass plate a, adjusting set-screw w, in

termediate piece, q, sliding casing n, upper movable brass padding, 0, lower stationary brass padding, 1), lower spring, 1", upper spring, 5, with the lid 12, hinge-bolt 0, having coiled spring f attached, lock-lever d, leverarm 6, and catch j, substantially as described, and for the purpose herein set forth.

In witness whereof I have hereunto set my hand and seal.
